Abstract:
The purpose of the present invention is to provide: an ultraviolet curable resin composition which has good coatability and curability, and in which bubbles generated inside the resin composition as well as bubbles present at the interface between an optical member and the resin composition when the optical member and resin composition are laminated are suppressed, and high visibility can be achieved; and a manufacturing method using the resin composition. Provided is an ultraviolet curable adhesive composition for touch panels, the ultraviolet curable adhesive composition being a resin composition for touch panels and being characterized in that, when the resin composition is placed in a container and stirred with a disperser at 200 rpm for 30 minutes in a 25°C environment to introduce bubbles, and then the container is placed in a bell-type vacuum defoamer, bubbles having a size of at least 100 μm disappear within 30 minutes under a reduced pressure environment in which the internal pressure is 500 Pa.
